Sheesh... I take two steps away from a conversation and have to spend an hour catching up... thankfully, the conversation hasn't changed much. I would like to throw in my towel (I've already tossed my two cents) and say that I believe both sides have stated their case.
And, it is my hope that Reason prevails. Both sides believe Reason to be on their side, and they're probably both right. If I might call upon my own analogy, that of the Aspiring Parents... I might suggest that when a couple is having a difficult time getting pregnant, sometimes taking a break, changing the scenery, "letting go", are just the catalyst the body(ies) need in order to function properly.
As the platform evolves during this formative year, it might be that Narrative decides that "ownership" is the wrong/right term and abstain-from/proceed-with changing the Niche structure to accommodate the most reasonable, rational point of view. But, if it continues to escalate, walls get higher, convictions are held tighter, and animosity (coupled with reluctance to change) multiplies.
In the end, whatever the rules are that govern the platform, it is still a tool. And people will use (and exploit) any and all tools any which way they can.
